Question

7 if producers receive 2000 units of energy, how many units of energy do primary consumers (herbivores) receive from these producers? a 1000 units b 2000 units c 200 units d 20 units e 2 units

Explanation:

Step1: Recall energy - transfer rule

In an ecological energy - transfer pyramid, only about 10% of the energy is passed from one trophic level to the next.

Step2: Calculate energy for primary consumers

The producers have 2000 units of energy. Primary consumers (herbivores) are at the next trophic level. So the energy they receive is 2000×0.1 = 200 units.

Answer:

C. 200 units
